| This report describes the di�erent algorithms implemented as part of the Visual Flythrough project. The main emphasis has been to implement algorithms for realistic rendering of volu� metric terrain. Functions have been implemented for handling various input data formats. A simple voxelization scheme has been implemented for generation of anti�aliased voxel terrain model. VolVis has been extended to support terrain models using a �at scene graph. Fast modeling and rendering has been achieved by using multiple CPUs on the system. Several sample terrains have been rendered to validate the utility of this scheme. The shared memory multiprocessor system recently has attracted a lot of attention because of its low cost and wide availability to the graphics researchers. In this work � we show practical parallel solutions to the following volume graphics �7 � problems � volume texture modeling � volume texture rendering � and voxelization for unstructured grid rendering. All these solutions process 2D and 3D arrays and employ multiple processors on the shared memory system. We present results for parallel execution time � parallel memory requirements and overheads for the three algorithms described in this work. We also present results of | |||||||||||||||
